Embodiment 1

[0031] (1) Take the fresh whole herb of Hutonghong, wash it, cut it into 2-4cm sections, add water of the same quality, place it in a homogenizer at 12000rpm for 3 minutes, and make a slurry;

[0032] (2) Add 20 times the volume of petroleum ether with a boiling range of 30-60°C to the slurry, extract at 50°C, separate the petroleum ether extraction components, concentrate the remaining slurry at 50°C and -0.085MPa to less than the weight of the original tiger tongue red, and obtain the infusion paste; the petroleum ether extract is condensed and recovered, which can be further used to separate the volatile oil;

[0033] (3) Add ethanol solution with a volume fraction of 70% to the extract, the solid-liquid ratio is 30mL / g, and the pressure is maintained at 200MPa for 8min;

[0034] (4) The extract obtained in step (3) is concentrated, put on a macroporous adsorption resin column, eluted with water, 30% ethanol, and 80% ethanol successively, collects the 80% ethanol eluate, co...

Embodiment 2

[0036] (1) Take the fresh whole herb of Hutonghong, wash it, cut it into 2-4cm sections, add water of the same quality, place it in a homogenizer at 6000rpm for 5 minutes, and make a slurry;

[0037] (2) Add 15 times the volume of petroleum ether with a boiling range of 30-60°C to the slurry, extract at 50°C, separate the petroleum ether extraction components, concentrate the remaining slurry at 40°C and -0.095MPa to less than the weight of the original tiger tongue red, and obtain the infusion paste; the petroleum ether extract is condensed and recovered, which can be further used to separate the volatile oil;

[0038] (3) Add an ethanol solution with a volume fraction of 60% to the extract, the solid-liquid ratio is 25mL / g, and the pressure is maintained at 100MPa for 10min;

[0039] (4) The extract obtained in step (3) is concentrated, put on a macroporous adsorption resin column, eluted with water, 30% ethanol, and 80% ethanol successively, collects the 80% ethanol eluate,...

Embodiment 3

[0041] (1) Take the fresh whole herb of Hutonghong, wash it, cut it into 2-4cm small pieces, add water of equal quality and place it in a homogenizer at 8000rpm for 4 minutes to make a slurry;

[0042] (2) Add 20 times the volume of petroleum ether with a boiling range of 30-60°C to the slurry, extract at 50°C, separate the petroleum ether extraction components, concentrate the remaining slurry at 45°C and -0.090MPa to less than the weight of the original tiger tongue red, and obtain the infusion paste; the petroleum ether extract is condensed and recovered, which can be further used to separate the volatile oil;

[0043] (3) Add an ethanol solution with a volume fraction of 65% to the extract, the solid-liquid ratio is 30mL / g, and the pressure is maintained at 150MPa for 9min;

[0044] (4) The extract obtained in step (3) is concentrated, put on a macroporous adsorption resin column, eluted with water, 30% ethanol, and 80% ethanol successively, collects the 80% ethanol eluate...

Abstract

The invention discloses a method for preparing ardisia mamillata extract. The method comprises the following steps: (1) washing fresh solid-liquid ratio, cutting into pieces, homogenizing with water to prepare slurry; (2) adding a petroleum ether extraction volatile component into the slurry, separating a petroleum ether extraction component, and concentrating the rest slurry to be less than the weight of previous ardisia mamillata to obtain extract; (3) adding an alcohol solution having a volume percentage of 60-70 percent into the extract in a solid-liquid ratio of 25-30mL / g, and insulatingthe pressure at 150-200 MPa for 8-10 minutes; and (4) concentrating the extract, passing through a microporous adsorption resin column, eluting with water, 30% alcohol and 80% alcohol sequentially, collecting the 80% alcohol eluted liquid, and concentrating and drying at reduced pressure to obtain the ardisia mamillata extract. The invention further discloses a method for detecting the ardisia mamillata extract. The method has simple steps and convenience in operation, and has high content of extracted saponin ingredient and accurate and reliable result.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a preparation and detection method of tiger tongue red extract. Background technique [0002] Hutonghong is a dwarf shrub belonging to the family Zijinbudae. It is a commonly used Chinese herbal medicine. The whole plant has the functions of clearing away heat, promoting blood circulation, and promoting muscle growth. It is used for traumatic bleeding, hepatitis, and cholecystitis. [0003] At present, the researches on the medicinal components of Tiger Tongue Red are all analyzed and processed after Tiger Tongue Red is dried, and part of the active ingredients have been lost during the drying process of Tiger Tongue Red. Therefore, how to provide a method for directly extracting and detecting the medicinal components of fresh tiger tongue red has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view...
